"Furnace Clean n Check" just $75

Why Get a Furnace Clean n Check?

  • Save Money and Energy: A clean heating system operates more efficiently and uses far less energy than one that has not been properly maintained. Having me clean your furnace every year will help your furnace working at optimal performance which saves you money in the long run.
  • Increase Comfort: Dirt buildup within the furnace can obstruct the flames from burning as hot as they should. This will decrease your comfort as you wait forever for your furnace to meet the temperature you need. I will personally scrub down your burners and the rest of the heating system, so you can enjoy reliable comfort all winter long.
  • Prevent Breakdowns: 90% of furnace breakdowns can be traced back to a lack of regular maintenance. Avoid the inconvenience and cost of frequent breakdowns, and have me clean your furnace yearly.
  • Increase Lifespan: The better you care for your furnace, the longer it will last! Lets prevent the need for premature system replacement.

No Breakdown Guarantee: When you have your furnace maintained by TStat Heating & Air your heating system is covered by our No Breakdown Guarantee. Should your system breakdown within the current heating season following a "furnace clean n check", we will return and waive the $75 initial service fee for that call!

"Air-Conditioning Clean n Check" just $75

Why get a Air-Conditioning Clean n check?

  • 90% of all air conditioning system failures are a result of little or no maintenance!
  • A dirty air conditioner could cost up to 50% more to operate than a system that has been properly maintained!
  • Air conditioning tends to fail most often on the warmest days of summer where the system capacity is maxed out. When your condenser is blocked with dirt you loose capacity causing your unit to be under sized and you end up with a warm house on hot summer days. 
  • Cooling your home with a dirty air conditioner can take up to twice as long as it would if the unit were cleaned regularly!
  • Well-maintained air conditioners can last 20 years or more, but a poorly maintained system will cost hundreds in repairs and will require replacement earlier than expected!

Benefits of Regular Air Conditioner Maintenance

  • Save Money & Energy: Clean air conditioners are able to transfer energy more efficiently. Less energy is wasted with each cycle and your energy bill will thank you for it!
  • Increase Comfort: Dust and dirt make it more difficult for your air conditioner to remove excess moisture and heat from the air and your comfort goes out the window. Eliminate the dirt and get comfortable again!
  • Prevent Breakdowns: Dirt interferes with the function of the most vital components in your air conditioner causing breakdowns. Minimize costly repairs and have TStat Heating & Air keep your air conditioner running clean.
  • Increase Lifespan: Get the most out of your air conditioner and prevent early investment in a new system by having Four Seasons keep your air conditioner in tip-top shape year after year.

No Breakdown Guarantee: When you have your air-conditioning maintained by TStat Heating & Air your system is covered by our No Breakdown Guarantee. Should your system breakdown within the current cooling season following a "air-conditioning clean n check", we will return and waive the $75 initial service fee for that call!
