"Lion Home Service installed my gas boiler system 5 yrs ago and have been doing checks on it ever since. Yesterday Matthew G came out for a check and discovered a leak and high pressure in the expansion tank which will require a replacement. He was very knowledgable and very patient explaining things to me and answering my many questions about why a new expansion tank was necessary for a 5 yr old boiler, how the system works, how much the new tank and installation would be and many other issues. I will be requesting him to do the job soon although all of the plumbers from Lion Home Service that I've dealt with in the past have been professional, reliable and thorough so I know I can trust any of them to do an excellent job. Lion Home Service really takes care of their customers."

Behold the Difference! Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".
"I called to get a third estimate on replacing my residential boiler. I was looking at replacing it because other contractors had advised that the cost of repairs was too high; repairing a 20 ye old boiler didn’t make economic sense. Gilles sent Justin over the next day, so very quick service. Justin gave me a ballpark price to replace it, which was more in line with what I thought was fair. He also gave me a very fair price to repair it — about a third of what the other contractors quoted. A good chunk money, but a much better option right now. Comparing what the three contractors told me, I’m confident that Justin had it all coveted. He then allowed me to video him, explaining what he did and what I should expect and look out for. He also sold me on their annual maintenance plan, which is a bargain because it includes evaporative cooler startup and shut down."

Heating and air conditioning services FAQs
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.
As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
