Have you been dealing with frustrating HVAC problems in Lothian? Whether it’s heating or cooling troubles, the team at Belair is made up of experienced technicians ready to make your home comfortable once again. Call 888.823.5247 to schedule your appointment.
Some Lothian houses have been standing for generations on beautiful properties, while others have been built in the last 10 or 20 years. That diversity means many different types of HVAC projects are encountered here. From upgrading decades-old systems to solving challenges in homes without ductwork, Belair is the HVAC expert Lothian can trust.
Here are a few reasons Lothian homeowners choose our team:
If there is anything wrong with your Lothian heating system going into the winter months, you’ll quickly notice a chill throughout your home. With persistent cold temperatures and damp conditions, you need reliable heating equipment to maintain a warm and comfortable space. The many services available from Belair make it easy to keep the whole family happy.
Often, a Lothian furnace will try to tell you that something is wrong before it fails. If yours is struggling to keep up with demand, making strange noises when running, or cycling on and off, don’t ignore those signs. Reach out to us for help today before a total breakdown occurs.
Furnace RepairAnnual maintenance is important for all heating systems in Lothian. If anything is developing inside the furnace, such as a belt wearing down or a flame sensor getting dirty, it will be caught during the service visit. Schedule yours before winter gets here so you’re ready for the cold weather.
Furnace MaintenanceHas your furnace reached the end of the road? This could be the case if it has recently broken down and needs an expensive repair, or if it is simply old and can no longer keep your whole home warm. We take care of the entire installation, including pulling permits and scheduling the inspection, and make sure the system is documented and covered.
Furnace ReplacementOur team understands the unique challenges of maintaining and servicing boilers throughout Lothian, including managing leaks around the fittings and valves, issues with uneven heat, or strange noises coming from the system. Don’t continue to deal with poor performance from your boiler when a professional technician is just a phone call away.
Boiler ServiceBetween the heat and humidity, summer in Lothian can get uncomfortable. While you can’t change the conditions outside, you can make your home more comfortable by working with Belair for the maintenance, repair, or installation of your cooling equipment.
Did you recently return home on a hot summer day to find your Lothian house far hotter than you expected? That’s never a nice surprise. We can identify the likely causes of your AC failure, such as a failed capacitor or a refrigerant leak, to make sure the rest of your summer is as comfortable as possible.
AC RepairThere are few things a homeowner can do that will be as helpful as scheduling annual AC maintenance. An annual maintenance visit is one of the easiest ways to prevent a mid-summer breakdown. During our visit, we inspect and clean your system’s key components, so you can set your thermostat with confidence, knowing that the equipment is up to the challenge.
AC MaintenanceAn aging air conditioner may struggle to keep a home cool. Even if your older unit is still technically working, it might not be getting the job done to an acceptable standard. Old and aging air conditioners tend to be less efficient and struggle to keep up with your Lothian home’s needs. A properly sized replacement can drastically improve your home’s comfort with a big boost in performance and efficiency.
AC ReplacementMany homes in Lothian rely on heat pumps, and it’s easy to see why. These are flexible pieces of equipment that can both heat and cool, depending on the season. Whether you already have a heat pump that needs service or repair, or you would like to have one installed, Belair is the right choice for the job.
Heat Pump ServiceDuctless mini-splits are a practical option for homes without traditional ductwork, additions, converted spaces, and rooms that need more independent temperature control. We can install, maintain, and repair ductless systems to help keep those spaces comfortable year-round.
Ductless ServicePoor air quality is a problem that is common to homes in Lothian, due to the amounts of pollen seen in the spring and summer months. If you’ve noticed persistent respiratory issues in your home among some family members, it might be low air quality that is to blame.
At Belair, we offer several air quality services that address this problem. The options we have available include high-efficiency filters, whole-house humidifiers and dehumidifiers, air purification systems, and even HVAC zoning. When you speak with our technicians about your air quality issues, we can recommend appropriate solutions to clean up that air and make sure the whole family is breathing freely.
Did you know we do more than just HVAC? The Belair team also includes licensed plumbers who are ready to solve whatever plumbing challenges you are facing. Many homes throughout Lothian use private wells and septic systems, meaning plumbing issues here can be complex. If other plumbers aren’t able to work on your system effectively, call us now for assistance.
We are experienced with all types of plumbing work, including toilets, water heaters, sump pumps, gas piping, drain lines, and more. When you reach out, we’ll chat with you about the problems you are encountering, and our team will quickly make a plan to resolve the issue. Most plumbing troubles can be resolved in a single visit, and if your situation is more complex, we’ll discuss it with you and explain the repair work that is needed.
Generally speaking, Lothian is a lovely place to live when it comes to weather. Throughout the spring and fall, idyllic conditions are common with comfortable temperatures and not too much humidity. During those months, spending as much time outside as possible is the norm for residents throughout town.
Summer and winter tell slightly different stories, however. In the summer, the combination of temperatures that are often in the 80s and high humidity levels can leave everyone sweating through their days. Then, in the winter, low temperatures frequently hit the 20s, and an average of 15 inches of snow falls each year. Between Lothian’s summer and winter conditions, homeowners need an HVAC system they can count on.

Most HVAC repair visits are completed in a single appointment; however, this depends on the complexity of the job and what the technician has on hand. Once our technician has diagnosed the issue, it typically takes just one or two hours to finish the repair. For replacements and installations, the job usually takes a full day, with the possibility that a second day will be required, depending on the specific scope of the project.

This allows us to pay our employees for their time, along with putting gas in the trucks and covering other expenses.

Dre was my technician today. He went above and beyond to ensure my system was in tip top condition. What and excellent employee that you have there. I see a bright future for this young man. Great tech skills and people skills. 🏆👍
Fast, very friendly, and very knowledgeable technician!
Didn't have any heat, and Abe was able diagnose and correct the issue in a reasonable amount of time.
Abe is one of Belair Engineerings top two service personnel!
Abe was one of the most thorough technicians. He spent a lot of time trying to flush the condensate line and provided several options for long term fixes. I’d request him again.
Friendly and exceptional customer service and maintenance. It is hard to find skilled maintenance techs and Abe was all the above.
The service members were great.
Justin arrived during the assigned timeframe and conducted a thorough inspection. He advised me on the electronic air cleaner and provided info on a replacement.
I am really pleased with the service I got from Brandon. He was obviously quite familiar with the kind of a/c I have and went over everything to make sure it would stay running in the upcoming heat. He also clearly explained what had been happening with my system. He is not only knowledgeable and competent, he is also quite a friendly and charming guy. I will definitely continue to use Belair Engineering if they employ technicians like him.
A very fast response to my problem of no air conditioning. Unfortunately after the originally diagnosed problems were fixed, the unit still was not working well. They sent out their emergency technician right away. Paul was just amazing and worked until after nightfall to get things up and running.
Because of the expertise & great service I have received over the years with my gas fireplace, I had Belair install a backup generator. I know I will receive the same great service with this piece of equipment.
respectful to owners property
Fast, efficient service, as usual.
Our HVAC unit was overflowing with condensate. Called Belair and a technician arrived the next morning at 9 AM to quickly fix the problem. The cost was covered by our service contract.
I would recommend your services to anyone
