What Our Clients Say

Real feedback from customers who trust us with their air conditioning systems throughout the year

We've been using ClearSpaceWay for seasonal maintenance for three years now. Their spring check-up caught a refrigerant leak before it became a major issue, saving us from a complete system replacement. The technician explained everything in detail, showed me the problem area, and provided a clear estimate. The autumn service was equally thorough - they cleaned the outdoor unit, checked electrical connections, and tested the heating mode. What impressed me most was their systematic approach: they follow a detailed checklist and don't rush through the job. The price is fair for the level of service provided, and I appreciate that they call a week before each seasonal appointment.

Quick response, professional work. My AC stopped cooling in July, and they came the same day. Fixed the compressor issue and did a full system check.

Elena Petrova

Plovdiv

Good service overall. The technician was knowledgeable and did a thorough cleaning of both indoor and outdoor units. My only note is that the appointment was scheduled for 10 AM but they arrived closer to 11:30. Would be nice to get a call if there's a delay. Otherwise, the work quality was solid and the system runs much quieter now.

Georgi Kolev

Varna

The service met my expectations. They performed the seasonal check and replaced the filters. The technician pointed out that my outdoor unit needs better ventilation, which I appreciated. The price was slightly higher than I expected for a standard maintenance visit, but the work was done properly. Communication was professional, though I had to call twice to confirm the appointment time.

Maria Stoyanova

Sofia, Mladost

Excellent value for money. I have three AC units in my office, and they serviced all of them in one visit. The team was efficient, cleaned up after themselves, and provided a detailed report for each unit. They also offered advice on optimal temperature settings to reduce energy costs. Highly recommend for business clients.

Ivan Yordanov

About ClearSpaceWay

Providing reliable air conditioning maintenance services across Sofia since our establishment

Our Beginning

ClearSpaceWay was established to address the growing need for systematic air conditioning maintenance in Sofia. We recognized that many property owners faced recurring issues with their cooling systems, often due to irregular servicing or inadequate seasonal preparation. Our founders, with backgrounds in HVAC engineering and building management, decided to create a service focused specifically on preventive care.

Starting with residential properties in central Sofia, we gradually expanded our operations to include commercial facilities and office buildings. Our approach has always centered on scheduled maintenance rather than emergency repairs, which helps clients avoid costly breakdowns during peak summer months.

What We Do

We specialize in seasonal diagnostics and maintenance of air conditioning systems. This includes pre-summer inspections, filter replacements, refrigerant level checks, and post-season system shutdowns. Our technicians are trained to work with various AC models, from split systems to central cooling units. Each service follows a detailed checklist covering electrical connections, drainage systems, thermostat calibration, and airflow measurements.

Our Approach

We operate on a schedule-based model where clients book maintenance appointments before seasonal transitions. Spring appointments prepare systems for summer operation, while autumn services ensure proper shutdown and winter protection. This timing reduces the likelihood of mid-season failures when demand for repair services peaks and wait times extend.

Our team consists of certified technicians who complete regular training on new AC technologies and maintenance protocols. We maintain service records for each client's system, tracking maintenance history, parts replacements, and performance metrics. This documentation helps identify patterns and predict when components may need attention.

Common Questions

Frequently Asked Questions

Find answers to the most common questions about air conditioning maintenance and seasonal diagnostics. Our team is here to help you understand the importance of regular service.

We recommend scheduling maintenance twice a year - once before the cooling season begins in spring and once before winter. This ensures your system operates at peak efficiency when you need it most. Regular seasonal checks help identify potential issues before they become costly repairs, extend the lifespan of your equipment, and maintain optimal energy efficiency. For commercial systems or units that run year-round, quarterly maintenance may be more appropriate. Our technicians can assess your specific situation and recommend the best schedule for your needs.

Our comprehensive seasonal diagnostic includes inspection of all major components: refrigerant levels, electrical connections, thermostat calibration, condensate drain lines, air filters, evaporator and condenser coils, fan motors, and overall system performance. We measure temperature differentials, check for unusual sounds or vibrations, inspect ductwork for leaks, and test safety controls. After the inspection, you receive a detailed report with findings and recommendations. This thorough approach ensures nothing is overlooked and your system is ready for the upcoming season.

Spring maintenance prepares your system for the demanding summer months when it will work hardest. During winter, dust and debris accumulate, seals may dry out, and components can deteriorate from lack of use. A pre-season check ensures refrigerant levels are correct, coils are clean for efficient heat transfer, electrical connections are secure, and all components function properly. This prevents unexpected breakdowns during hot weather when repair services are in high demand and temperatures are uncomfortable. It also helps your system run more efficiently, reducing energy costs throughout the cooling season.

Several warning signs indicate your system needs attention: weak airflow, warm air from vents, unusual noises like grinding or squealing, frequent cycling on and off, moisture or leaks around the unit, unpleasant odors, and significantly higher energy bills. If your system struggles to maintain set temperatures or takes much longer to cool your space, this also signals a problem. Don't ignore these signs - early intervention prevents minor issues from becoming major repairs. Contact us immediately if you notice any of these symptoms, especially during peak season when delays can be uncomfortable and costly.

A well-maintained system operates 15-20% more efficiently than a neglected one. Clean coils transfer heat more effectively, proper refrigerant levels ensure optimal performance, and lubricated moving parts reduce friction and energy consumption. Dirty filters force the system to work harder, while clogged condensate drains can cause the unit to shut down. Regular maintenance keeps all components working together efficiently, reducing the amount of electricity needed to cool your space. Over time, these savings add up significantly, often covering the cost of maintenance itself while extending equipment life and preventing expensive emergency repairs.

Yes, there are several tasks homeowners can safely perform. Replace or clean air filters monthly during heavy use periods. Keep the outdoor unit clear of leaves, grass clippings, and debris within a two-foot radius. Ensure vents and registers inside are not blocked by furniture or curtains. Check the condensate drain line occasionally to ensure it's not clogged. Keep the thermostat away from heat sources that might affect its readings. However, tasks involving refrigerant, electrical components, or internal mechanisms should always be left to certified professionals. These DIY steps complement professional maintenance but don't replace it.

Maintenance is preventive care performed on a functioning system to keep it running efficiently and prevent problems. It includes cleaning, adjusting, and inspecting components according to a schedule. Repair services address specific problems or failures - fixing broken parts, replacing worn components, or resolving performance issues. Think of maintenance as regular health checkups that keep you well, while repairs are like medical treatment when something goes wrong. Regular maintenance significantly reduces the need for repairs by catching small issues early. Our seasonal diagnostic services focus on prevention, though we can address any problems discovered during inspection.

A thorough seasonal maintenance visit for a residential system typically takes 60-90 minutes. This allows our technicians to carefully inspect all components, perform necessary cleaning and adjustments, and test system performance. Larger systems or commercial units may require more time. If we discover issues requiring immediate attention, we'll discuss them with you before proceeding with any additional work. We never rush through maintenance - thoroughness is essential for catching potential problems. We schedule appointments with adequate time between visits to ensure each system receives the attention it deserves without feeling hurried.

Yes, we offer comprehensive maintenance plans that provide scheduled seasonal services at preferred rates. Plan members receive priority scheduling, discounts on repairs if needed, and reminders when service is due. These plans ensure you never miss important maintenance and provide budget-friendly payment options. Different tiers are available depending on your system type and needs. Members also receive extended warranty coverage on parts and labor for certain repairs. A maintenance plan is an investment in your system's longevity and your peace of mind. Contact us to learn about current plan options and pricing for your specific situation.

If we identify any issues during maintenance, we'll explain the problem, its potential impact, and recommended solutions before proceeding. We provide clear pricing for any additional work needed and never perform repairs without your approval. Minor adjustments and fixes are often included in the maintenance service. For more significant issues, we'll prioritize them by urgency - some may need immediate attention while others can be scheduled for a future visit. Our goal is transparency and helping you make informed decisions about your system. We'll always present options and work within your budget whenever possible.

Absolutely. Even new systems benefit from regular maintenance, and most manufacturer warranties actually require it. New equipment still accumulates dust, experiences normal wear, and needs periodic adjustments to maintain peak efficiency. Starting a maintenance routine from day one establishes good habits and maximizes your system's lifespan. Many problems that develop in "new" systems are actually due to installation issues or initial break-in period adjustments that maintenance visits can catch early. Regular service from the beginning ensures your investment is protected and your system performs as designed throughout its expected lifespan of 15-20 years.

We provide seasonal maintenance and diagnostic services throughout Sofia and surrounding areas. Our service area includes central districts like Lozenets, Oborishte, and Sredets, as well as residential neighborhoods such as Mladost, Lyulin, Druzhba, and Vitosha. We also serve businesses and homes in Studentski Grad, Manastirski Livadi, and Boyana. Our technicians are familiar with the specific climate challenges in different parts of the city and can provide tailored recommendations.

Scheduling is easy - call us at +359 88 514 9732 during business hours, or email [email protected] anytime. We'll discuss your system type, any concerns you have, and find a convenient appointment time. We recommend booking spring maintenance in March or early April before the rush, and fall maintenance in September or October. Early scheduling ensures you get your preferred time slot and your system is ready when you need it. For maintenance plan members, we'll contact you automatically when service is due. We offer flexible scheduling including some weekend appointments to accommodate your schedule.

Preparation is minimal but helpful. Ensure our technician can access both indoor and outdoor units - clear any stored items blocking access. If you have pets, please secure them in another area. Make a note of any concerns or unusual behavior you've noticed with your system. Have your previous maintenance records available if possible. If your thermostat is locked or programmed with special settings, be prepared to provide access or explain the settings. There's no need to clean the unit yourself - that's part of our service. Simply ensure safe, clear access to all components and be available to discuss any questions or findings during the visit.

We accept multiple payment methods for your convenience: cash, bank transfers, and major credit/debit cards. Payment is due upon completion of service unless you're enrolled in a maintenance plan with different billing arrangements. We provide detailed invoices for all services performed, including a breakdown of work completed and any parts used. For larger repair work discovered during maintenance, we can discuss payment options before proceeding. Business clients can arrange invoicing terms suitable for their accounting processes.
