One of the most important yet bothersome areas of service and repair for many homeowners is their HVAC system – heating, ventilation, and air conditioning. Climate control systems; an important aspect of new construction, home renovation, and home repair certain to confront every home owner at one time or another.
Because principles involved in air conditioner cooling heating systems vary, depending upon the type of cooling and heating system used, a basic understanding how each works is important.
HVAC systems fall into one of two categories; local or central. Local heating is a type of ductless heating system; providing heat to a single, localized area. Local cooling heating sources include fire places, electric radiators, space heaters, window unit air conditioners, pellet and wood stoves, fans, etc.
Central cooling heating systems distribute hot water, steam, or air throughout a structure. This is accomplished through a network of ducts or pipes, depending upon system type. For obvious reasons, cold climate areas most often use central heating as their major heat source.
A central cooling heating unit contains a boiler, furnace, or heat pump; to heat water, steam, or air at a centralized location before distribution throughout a building by way of piping or ductwork.
Heated water or steam flows from the heat pump, or boiler heating hydronic system into pipes. The pipes connect to a baseboard heating system, convector, or radiator that distributes heat throughout that room. Some systems have one pipe that connects to each fixture; other systems have two.
A central heating system that uses forced air feeds a series of ductwork that connects to vents, strategically placed in the coldest part of the room. This would typically be next to windows to minimize condensation, or along external walls. A second system of ducts circulates cold air back to the furnace.
Ventilation exchanges inside air with outside air; removing moisture, odors, airborne bacteria, heat, and smoke. Improving air quality. And, of course, air conditioning helps keep inside air at a comfortable level.
The heating, ventilating, and air conditioning functions associated with HVAC units are all closely interrelated. Combined, they provide a comfortable temperature with sufficient humidity, and improved indoor air quality for suitable indoor living conditions.
Planning a home renovation addition or an old home renovation project may require expansion of the HVAC system. Homeowners should keep the following in mind:
Another alternative to expanding your cooling heating system, and an increasing popular one, is to install a radiant heating system. This system heats using electrical wires or hot-water tubing inserted behind the finish surfaces of walls, ceilings and floors.
Large scale installations of this type system are not a diy project; services of a special trade or knowledgeable residential general contractor are required.
When it comes to hiring the right contractor for new HVAC installation or HVAC unit expansion, keep the following in mind:
When you have found 2 or 3 contractors you consider good candidates, provide each with an identical detailed description of your project, and collect bids. Once you have selected the HVAC contractor you feel most comfortable with, draw up a contact with detailed information.
The contract should include the names, addresses, and telephone numbers of both parties, and the legal address of the renovation site. It should contain a detailed job description, starting and ending dates, a detailed materials list, labor and materials costs, payment schedules, who is responsible for obtaining permits, and anything else pertinent to the project.
Meet with the contractor and go over the contract before signing it. Both the contractor and the project owner should sign the contract, each retaining a copy for their files.
